    Abstract:
    Cutis verticis gyrata (CVG) is classified as primary or secondary according to the absence or presence of underlying soft tissue abnormalities. We report an infant with Turner syndrome (TS) who in addition presented with CVG on the scalp. The skin biopsy revealed a hamartoma-like lesion. We reviewed the clinical and histopathological findings of the 13 reported cases of congenital CVG in patients with TS, including ours. In 11 of them, CVG was localized on the skin of the scalp, mainly on the parietal region, and in two, on the forehead. Clinically, CVG had a flesh-colored aspect, with absent or sparse hair, and was not progressive. CVG was classified as primary in four patients who had skin biopsy and it was attributed to the intrauterine lymphedema of TS. However, histopathology in two of these patients identified dermal hamartoma as a secondary cause of CVG, and in three others, including ours, there were hamartomatous changes. Although further studies are required, previous findings support the proposal that some CVG may instead be dermal hamartomas. This report alerts clinicians to recognize CVG as a low-frequency manifestation of TS, but also to consider the possible co-occurrence of TS in all female infants with CVG.
